CARBON MONOXIDE
Sentry and Sentry Plus are equipped with an electronic carbon monoxide (CO) sensor. The
sensor continuously monitors the concentration of CO and alerts you of dangerous levels via
in-app visual and audible alerts. The sensor has a life span of ten years and cannot be
replaced.
CO LEDs
Sentry and Sentry Plus are equipped with three LEDs. The
middle LED corresponds to CO concentration. When elevated
levels of CO concentration are detected, the LED changes color
according to the amount of CO detected.

ForeFlight Mobile Alerts
ForeFlight warns of elevated CO concentration with an in-app audible and visual pop-up
notification. The audible notification is played on the iOS device (or through a connected
headset). The audible notification is read aloud by the iOS device’s default voice and will state,
“Caution, Sentry carbon monoxide level is eighty parts per million.”
The visual pop-up notification appears on any ForeFlight Mobile view (Maps, Flights,
Documents, Etc.) and includes the specific CO concentration. Tap the notification to hide it for
five minutes.
If elevated levels of CO concentration exist after five minutes, the notification will be displayed
again. If CO concentration increases to dangerous levels, another visual pop-up and audible
notification will be displayed even if the previous notification was muted.
